Abstract
A guideway for a magnetically levitated railway is described, having a longitudinal stator linear drive comprising at least two parallel stators. The guideway includes a plurality of supports (1) arranged along a given line and adapted to form straight and curved guideway sections and stator sections mounted on the supports (1), these sections being composed of straight stator end packs (6a, f; 7a, f) and likewise straight middle stator packs (6b-3; 7b-e) arranged therebetween, the packs in the region of the curved guideway sections being laid in the manner of polygonal trains to form outer and inner stator sections (6, 7) and being separated from one another by gaps (23, 24). The stator end packs (6a,f; 7a,f) and the middle stator packs (6b-3; 7b-e) have a predetermined tooth/groove pitch (16) with reference to a conceptual space curve (2) and different “ideal” lengths which differ from one another by fractions of a tooth/groove pitch (16). The middle stator packs (6b-3; 7b-e) are so combined with one another in at least one outer or inner stator section (6, 7), taking into account their different “ideal” lengths, that a “material” total gap bet…
